Matt Damon Discusses "Bourne" Plot Details

While promoting "The Martian," Matt Damon was answering questions about the new Jason Bourne film, revealing a few plot details in the process.

"[Bourne] has his memory back, but that doesn't mean he knows everything," said Damon. "It's 12 years since Jason Bourne has been on the grid. So we have to answer the questions, Where's he been? What's he doing? What gets him going again? So once we solved all that, then we had a movie."

The actor went on to say that the film will focus on the US living in a "post-Snowden" society, which means there will be government surveillance and privacy issues.
